5 Technical description
5.1 Intended use
The negative pressure unit Compact 100.000 serves for the filtration of non-condensing
asbestos contaminated air, in temperature rage up +45 °C, with external exhaust for the
air. During asbestos sanitation works within closed rooms, you must avoid that asbestos
fibres leave the sanitation area and in this way endanger humans and the environment.
For these reasons, the sanitation areas (also called dirty area) have to be separated from
the clean area with the help of a negative pressure unit and kept under dynamic negative
pressure.
An integrated filtering system establishes the conditions that the asbestos concentration
in the exhausted air does not exceed max. 1000F/m³. The exhausted air is blown in the
open air.
The device is not appropriate for the filtration of flammable gas or dust.

5.5 Information about the filter change
The frequency of the change of filter depends on the degree of pollution of the filter. If the
clogging of the filter increases (contamination of the filter), the air capacity decreases.
For the control of the filter during the operation, the device is equipped with a manometer
and a signal light.
Important: Use only authorised, faultless filter!
With filter of new condition, approximately 950 Pascal are displayed on the gauge.
(Evaluated at 100 % capacity)
We recommend a filter change at about 1400 Pascal (indicator light filter monitoring is
on)
To determine which filter (main filter, bag filter or pre-filter) is dirty, at a value on the
pressure gauge of about 1400 Pascal, do as follows:
1. Exchange the pre and bag filter and switch on the unit
2. Pressure gauge value 950 - 1150 Pascal => continue to operate the unit
3. Pressure gauge value > 1150 Pascal => exchange the main filter
